About This Dataset
Countries by Nuclear Energy Share of Electricity 2025
Countries ranked by the percentage of national electricity generation derived from nuclear power plants in 2025, according to IAEA Power Reactor Information System and IEA Electricity Statistics. France generates approximately 70% of its electricity from nuclear power — the highest share of any large economy and the product of a deliberate energy policy decision made after the 1973 oil crisis to achieve electricity independence through a standardised fleet of pressurised water reactors built at industrial scale by state utility EDF. This nuclear dependency has given France among the lowest carbon intensity electricity in Europe and among the cheapest wholesale electricity prices, though it has created a concentration of infrastructure risk that became apparent during the drought-related reactor cooling crisis of 2022.
Analysis
The top three in Nuclear Share of Electricity (%) in 2025 are France (70), Slovakia (58) and Ukraine (55). The 8 entries cover a range of 51.4, from 70 down to 18.6. First and second are separated by 12, so the leader sits inside the field rather than apart from it. The field is close behind: 5 of the 8 sit at half the leader's figure or above (35+).
